“project cannot be loaded it may be damanged…”

I am using Premiere CS6 on a Macbook Pro and am in the middle of editing a huge project. I went to open the project today and got this error.

 

“the project cannot be loaded it may be damaged or contain outdated elements”

 

I have no idea how or why this is happened.

 

PLEASE HELP!

 

What I have tried:

 

 

1. Starting a new project and importing the entire project. I get the same error message.

 

2. Starting a new project and importing just the sequences. Premiere just stalls.

 

3. Cleaning the Media Cache.

 

4. Uninstalling then re-installing Premiere.

 

5. Importing the project into After Effects. I get an error message.

 

6. The auto-save files open, but the latest one is quite old.

 

7. Duplicating the project file.

 

8. Moving the project file and file structure to a new directory.

 

 

None of these have worked!

 

 

Any other ideas?
